We are please to announce The GTM supercharger system Development for the 370Z . The GTM supercharged 370z project was under way back in the begging of the year .

Since we are completely done with our twin turbo system development that was released last month, We will be focusing on the the supercharged system. We are committed and planing on displaying both of our force induction system Solution for the 370Z @ sema 2009 .

Our GTM supercharger system will be utilizing the Rotrex C38 supercharger, The Key to the Rotrex supercharger's unique compactness, efficiency, low noise and reliability is its state of the art traction drive technology.

Great speeds and low noise are just some of the advantages of traction drives over traditional gear transmissions. Traction drives transmit power through friction forces between its rolling elements.

The Rotrex patented traction drive uses an elastic annulus with a small pre-span to secure contact between the roller planets and the sun shaft with a reasonable force. The patented "ramp effect" increases efficiency and reliability in the transmission by regulating the torque transfer capability on demand through self-adjusting planet geometry.

To enhance performance, the Rotrex traction drive uses a special traction fluid. These fluids are a new family of synthetic hydrocarbon oils and greases offering a series of unique performance advantages. Developed specially for its use in Rotrex superchargers, the SX100 momentarily increases viscosity under high surface pressure, enhancing the traction drive performance by securing the optimum friction between rolling elements while cooling and protecting the system.

This traction drive combined with the latest technology in centrifugal compression, characterized by high adiabatic efficiency and low noise, gives Rotrex superchargers an exceptional competitive edge over any other forced induction solution.

The GTM Supercharger Will Have three different stages to offer

Stage one will come with C38-61 Trim up to 550 HP
Stage two will come with C38-71 trim up to 590 HP
Sage three will come with C38-81 trim up to 630 HP

Here is some pics of the the Rotrex C38-61

The GTM Supercharger kit will Have four different Rotrex compressors to chose from: C38-61 Trim,C38-71 trim, C38-81 trim,C38-91. Combined with our custom compressor housing we will offer three different stages .

Stage zero up to 450 HP (carb approval pending)
Stage one up to 500 HP
Stage two up to 525 HP
Stage three up to 550 HP

All of our Supercharger kits are available in two forms. The tuner kit form, so the professional and the end user have the flexibility of choosing what ever fuel and engine management they may desire and feel comfortable using. The second option being a complete kit including fuel and engine management solutions. With that being said, GTM will also offer an extensive range of fuel system and engine management modules to go with our Supercharger kits.
